how to keep desktop resolution on htpc?
 

hi, i connected my HTPC running Devuan beowulf to my Sharp 70" AQUOS LED 4K UHD and set the desktop resolution at 1920x1080.

However, very often when i open the TV, the desktop seems to automatically adjust to 4k (3840 x 2160), when i reverted back to 1080p resoluton, it will change again to 4k after a while, and the fonts will become too small to read.

how to keep the desktop at 1080p?

In case you want to keep just one resolution you can put it in xorg.conf as the only mode.

probably you need to disable the auto detection of the display and hardcode the config you need.
